Abstract

Thermoelectric elements with excellent thermoelectric characteristics such as Seebeck coefficient thermoelectromotive force and thermal conductivity can be produced by molding a powder of metal or metal alloy as the raw material and then sintering; by using as such raw material, ultra fine powders containing Fe and Si as main components and having a mean particle diameter of 50 to 5,000 Å.
